Jackson creates the model shown in the diagram. He forms a clay mountain at the bottom of a plastic container and adds water to the container. Jackson then places a lid on top of the container and a petri dish filled with ice cubes on top of the lid. Next, he places a lamp over the container and turns it on.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
